Neorhapdopsis gen. nov.

Type species: Neorhabdopsis lutzei spec. nov.; here designated as the type species for the genus.

Etymology: The generic name is a combination of the Greece word Neo meaning new and Rhabdopsis that refers to the similar African genus.

Description: Length & habitus: elongate; blind with reduced elytra and long abdomen; small species of about 1.5–2.0 mm.

Head approximately quadrate; clypeus semicircular; sinuate in front of base of antennae; labrum rectangular; eyes absent; setiferous punctation; without distinct neck.

Antennae not geniculate; first antennomere thick; width of antennomeres increasing from second antennomere to apex.

Pronotum quadrate or slightly longer than wide; widest in middle or close to anterior angles; in posterior half convergent; lateral margin fine; with setiferous punctation.

Elytra transverse; shorter than pronotum; divergent from shoulders to posterior edge; hind wings reduced; with suture and suture lines; with setiferous punctation.

Abdomen densely and coarsely punctate; punctures with long setae.

Protibia enlarged; inner edge emarginated, with comb; in posterior aspect, totally visible; outer edge with spines inserted directly on edge; posterior face with few long setae; tarsi pentamere.

Aedeagus with spiral endophallus; apical lobe curved; paramera present; with one or two long setae at apex.

Diagnosis: Similar to the African genus Rhapdospsis FAGEL, 1959 in the yellow colouration, shape of pronotum, short elytra and absence of eyes. However, the aedeagus of these two genera is different: the aedeagus of Rhapdospis has no parameres and is nearly gobular, whereas the aedeagus of Neorhapdopsis has distinctive parameres with one or two apical long setae.
